PEP 425:
* "The version is py_version_nodot. CPython gets away with no dot, but if one
is needed the underscore _ is used instead"
I don't particularly like replacing dots by underscores. That needed because
you use the dot character in compressed tag sets, but why not use a comma to
separate items in the compressed tag set?
* "The platform tag is simply distutils.util.get_platform() with all hyphens -
and periods . replaced with underscore _."
Why the replacement? The need for replacement could be avoided by using a
different separator between elements of a tag (for example "~" or "+"), and
furthermore the platform tag is at a know
location, and hence the use of hyphens in the platform tag is harmless (use
"python_tag, abi_tag, platform_tag = tag.split('-', 2)" to split the tag into
its elements.
* "compressed tag sets"
Using '"," instead of "." to separate elements of the tag set takes away the
need to replace dots in tag elements, and seems more natural to me (you'd also
use comma to separate the elements
when you write them down in prose or python code.
